Low-velocity impact properties of shape memory alloy (SMA) wires and carbon
ber reinforced poly
(butylene terephthalate) obtained by resin transfer molding were characterized. At the subcritical regime the
dissipated energy is not affected by the presence of the wires. However SMA has a positive effect on the
maximum absorbed energy, since the maximum allowable load is higher. The contribution of the SMA wires
to the higher impact performance of the hybrid composite is suggested to be due to their energy absorbing
capability, and also to the high reversible force that acts as a healing force.
